Application June 2, 1937, Serial No. 146,106

Renewed March 9, 1939 Claims. (Cl. 85-1) This invention relates to studsespecially adapted for use in lieu of shoulder screws or screws and locknuts on stripper plates, knockout plates or pads and the like on sheetmetal dies and has for the primary object the provision of an efiicientnon-breakable and inexpensive device of this character which may beemployed as a pilot for the die spring and will limit the distance oftravel of the stripper plate or other similar element as above mentionedand the die shoe away from each other and yet permit,

free travel towards each other and may be easily and quicklyassembledfrom the side in which the springs and stripper plate or otherelement are assembled.

With these and other objects in view, this invention consists in certainnovel features of construction, combination and arrangement of parts tobe hereinafter more fully described and claimed.

For acomplete understanding of my invention, reference is to be had tothe following description and accompanying drawing, in which Figure 1'is 'a fragmentary'vertical sectional view showing a stripper plate anddieshoe connected by a stud constructed in accordance with my invention.I v

Figure 2 is a side elevation, partlyin section, illustrating the studdetached from the stripper plate and die shoe.

Figure 3 is an .end View showing one end of the stud.

Figure 4 is an end view showing the other end ofthe stud.

Figure 5 is a sectional view taken on the line 5--5 of Figure 2.

Referring in detail to the drawing, the numeral I indicates afragmentary portion of a stripper plate and 2 a fragmentary portion of adie shoe. Interposed between the stripper plate and die shoe is a coilspring 3 seating in a socket 4 formed in the die shoe. The stripperplate and die shoe are found in the construction of sheet metal dies andin order that these parts be joined for free movement towards each otherand for limiting the movement away from each other my invention isemployed and which also by extending through the spring 3 acts as apilot therefor. The stripper plate and die shoe have axially alinedopenings 5 in which are received the end shanks 6 of my invention whichincludes a pair of interconnecting links 8 each of substantiallyrectangular shape and split to permit the assembling of the linkstogether. As shown, the

bore of the opening 5 in the stripper plate I is plain and smooth butthe bore of the alined opening 5 of the die shoe 2 is screw-threaded.

The shanks 6 are integral with the links and each screw-threaded fromits outer end to an inner base shoulder andthe splits in the links alsoextend through the shanks. The parallel side portions of the links havebeveled faces 9. The beveled faces of one link have sliding con-, tactwith the beveled faces of the other link. One of the shanks is drilledaxially and internally screw-threaded, as shown at 10, in which may bethreaded a suitable tool to aid in the assembly of the stud of myinvention in the die shoe and stripper plate.

To assemble the stud the non-socketed shank thereof is threaded in theopening of the die shoe and the spring 3 placed to surround the stud. Inorder to draw the socketed shank through the opening inthe stripperplate a suitable tool is passed through the opening of the latter andthreaded in the .socketed shank so as to draw the same through theopening of the stripper plate and permit a nut II to be threadedthereon. The stud of the construction described will limit distance oftravel between the stripper plate and die shoe under the influence ofthe spring, also act as a pilot for the spring and permit free travel ofthe stripper plate and die shoe towards each other. i

What is claimed is:

1. A stud comprising interconnected links capable of a limited slidingmovement relative to each other and each split at one end, split screwthreaded shanks integral with the split ends of the links, one of saidshanks having a threaded socket to receive a threaded tool.

2. A stud comprising interconnected links capable of a limited slidingmovement relative to each other and each split at one end, split screwthreaded shanks integral with the split ends of the links, one ofsaidshanks having a threaded socket to receive a threaded tool, each of saidlinks being of substantially rectangular shape and the side portionsthereof having beveled faces so that the beveled faces of one link mayslide upon the beveled faces of the other link.

3. A stripper plate mounting stud of the character described comprisinginterlooped substantially rectangular open link members providinglimited free axial movement but precluding appreciable relative angularor lateral movement between the members, one of said'members beingprovided with means at its outer end portion for rigid connection to adie shoe and the other with opposed means at its outer end portion forrigid connection to a stripper plate.

4. A stripper plate mounting stud of the character described comprisinginterlooped substantially rectangular open links providing limited freeaxial movement but precluding appreciable relative angular or lateralmovement between the links, said links being formed at remote ends withintegral axially alined screw shanks for connecting them respectively toa die shoe and a stripper plate.

5. A stripper plate mounting stud of the char,-

acter described comprising interlooped substantially rectangular openlinks providing limited free axial movement but precluding appreciablerelative angular or lateral movement between the links, said links beingformed at remote ends with integral axially alined screw shanks forconnecting them respectively to a die shoe and a stripper plate, therespective links being split longitudinally through the axes of theirshanks and adjacent body portions.
